ABSTRACT
In this chapter, we will summarize the important points from the 12 chapters contained in Part 2 on modelling of tsunami generation and propagation.
In Chapter 6, Nirupama et al. reviewed the classical concepts on the two types of dispersion that is relevant for tsunami dynamics. The frequency of phase dispersion occurs during the propagation of tsunamis, and it specifies the manner by which different frequencies propagate with slightly different velocities. On the other hand, amplitude dispersion also referred as non-linear effects dominates in the coastal aspects of tsunamis. The Ursell number sets out the criteria by which one can choose which types of models one should use in different phases of a tsunami event.
